"php -f" can work!but not with apache

[gxlzlu]

I have built my extention for php4. There is not any error during compiling. PHP4 can work when I use "php -f test.php". So I try to install it to my Redhat7.2 system with apache.All my operation is followed:
(after compile the php4)
./killall httpd

./configure --enable-mymodule --with-apax=/usr/sbin/apxs --with-config-file-path=/etc

./make

./make install

cp php.ini-dist /etc/php.ini

(start apache again)

The test.php file likes this:
<?php
echo my_func()
?>
the func "my_func" only return "hello world". but when I access it by IE(another pc),I got "fatel error: undefined func....."

how could I do now???? Please help me!!!!
Thanks!!!!

My purpose is not only to say "hello world" but also build other functions that php can not support. So I built a extention for php. But now I can not install it with apache. Of course it work by "php -f test.php". So what should I do now???? thanx!!!

And I use "phpinfo()" to test. I found the new version has been installed but not support my module. And the configure section show it has "enable" my module. Why????
Thanx!
